/* This is a re-usable vue component for rendering a button
   that will probably be sending off ajax requests and need
   to show the loading status by setting the `loading` option.
   This can also be used for initial page load when you don't
   know the action of the button yet by setting
   `loading: true, label: undefined`.

  Sample configuration:

  <loading-button
    :loading="true"
    :label="Hello"
    @click="..."
  />
